JOI-IANN TRAUGOTT I-IOI-IBERGER, OF CHICAGO, ILLINOIS, ASSIGNOR, BYDIRECT AND MESNE ASSIGNMENTS, TO ARTHUR R. MORSE, OF CHICAGO, ILLINOIS.

CANDY-CUTTING MACHINE.

To all whom it may concern Be it known that I, JOHANN TRAUGOTTHonnnnenn, a, subject of the Emperor of Germany, residing at Chicago,county of Cook, and State of Illinois, have invented certain new anduseful Improvements in Candy-Cutting Machines, of which the following isa description. I

My invention-relates to'means for dividing, cutting, or otherwisesuit-ably forming into pieces of suitable length a strip of candy orlike material preferably while the same is in a plastic or semi-plasticcondition. The object of my invention is to provide a simple, durable,and efficient device of the kind described wherein the relativemovements of the cooperating cutting blades as they approach each otherduring the cutting operation are arranged to suit the requirements ofthe particular material upon which the device is adapted to operate.

To this end my invention consists in the novel construction,arrangement, and combination of parts herein shown and described, andmore particularly pointed out in the claims.

In the accompanying drawings, wherein like or similar referencecharacters indicate like or corresponding parts; Figure 1 is a sideelevation of mydevice. Fig. 2 is a top plan view of the samev with partsremoved and broken away to more clearly show the construction. Fig. 3 isa perspective view of the cover, or outer cam plate for assisting incontrolling the movement of the cutting blades. Fig. 4; is a perspectivedetail of the stationary inner cam for assisting in controlling themovement of the blades. Figs. 5 and 6 are details of the inner camsupport and itsassociated parts. Fig. 7 is a detail of a portion of oneof the blade carrying members. Fig. 8 is a perspective detail of ablade. Fig. 9 is an enlarged section taken substantially on line 9-9 ofFig. 1; and Fig. 10 is an enlarged section through the cutting headstaken substantially on line 1010 of Fig. 2.

In the preferred form shown in the drawings, my device consists of apair of rotatable shafts 1 and 2, each mounted in suitable Specificationof Letters Patent.

bearings upon the frame of the machine. Cutter heads or members 4 and 5are mounted upon the extremities of the shafts 1 and 2 respectively andare each rigidly secured thereto, the relative position of the partsbeing such that the periphery of the members 4: and 5 will be broughtinto suitable relation with each other so that the cutting blades 6-6positioned upon each head will be brought into suitable relation witheach other to substantially sever the material passing between them. Theheads 4: and 5 may be of anyv suitable construction and are preferablysubstantially similar. As shown each of the heads is provided with aperipheral wall 7 having a concentric flange 8 projecting at each side,a web or plate 9 having a central hub 10 is formed integral with orrigidly secured to the wall 7 for securing the head in position upon theshaft, and an inwardly projecting flange 11 is provided at the oppositeedge of the wall 7 thereby providing a chamber 12 within each headbetween the plate 9 and flange 11 extending to the wall 7 Any desirednumber of substantially radial or otherwise suitably arranged slots 14.-are provided in the periphery ofeach head extending inward beyond thewall 7 and terminating at a substantially uniform distance from thecenter of the member. The blades 6-6 which are preferably ofsubstantially uniform width are positioned in these slots and adapted tomove substantially radially of the member.

Any suitable means may be provided for controlling the position andmovements of the blades 6 in the heads 4 and 5. As shown a pair ofplates 15 and 16 are secured to the outer face of each member to closethe ends of the slots 14: and control the transverse position of theblades 6 in their respective slots.

The radial position of the blades may be controlled in any desiredmanner, as shown a pair of stationary cams or guides are providedadapted to engage the blades between them. In this form a cam 17 orequivalent means is rigidly positioned in each chamber 12 so that as thehead revolves the inner edge of the blades 6 will successively engagethe face of the cam to force them outward. A cover plate or cam 18 isarranged to par tially inclose the members 4 and 5, suitably formed toengage the outer edges of the blades 6 to control the outward movementthereof. In the form shown, the cam 18 is formed to hold the bladessnugly at the inner limit of their movement in their respective grooves14 until they arrive at a point where the blades engage the cam 17; atthis point the cam 18 is formed to correspond with the form of the cam17 so that at this point the cams coiiperate first to move the bladesoutward and then to return each blade to its normal position, themovement corresponding to the peculiar form of the cams. Obv ously thesecams may be formed to provide for any desired movement of the blades atanypoint in the rotation of each head depending upon the particularmaterial upon which it is intended that the machine is to operate. Inthe form shown, these blades are arranged to move outward tosubstantially the limit of their movement, after which they arepermitted toreturn to their normal position in the member the returnmovement being so adjusted that the cooperating blades will approacheach other with a substantially uniform movement.

Any suitable means may be provided for directing the material to beoperated upon into the space between the members 4 and 5. In the formshown, a suitable opening 19 is provided in the plate 18 and an inclinedcurved lip 20 arranged to direct the material to, and support andcontrol the same until it is engaged by, the blades 6, a suitableopening 21 is also provided at the opposite side of the plate 18 topermit the discharge of the material from the space between the members.A guide or chute 22 is provided to direct the discharged material onto aconveyer or other suitable means for disposing of the same.

Any suitable means may be provided for supporting the various parts inposition. In the form shown, two brackets 24 and 24 are provided eachrigidly secured to a base or foundation plate 26. The shaft 1 issupported in suit-able bearings formed integral with or rigidly securedto the respective brackets. The .shaft 2 may be similarly mounted, butin the preferred construction shown, a suitable opening 29 is providedin each of the brackets with the top and bottom wall of each openingsubstantially horizontal. A bearing 30 of suitable height to snugly fitwithin the opening 29 and arranged to move horizontally therein topermit of side adjustment is provided. Suitable means are provided forcontrolling the position of the bearing 30 in the opening 29. In thebracket 24 adjusting screws 31 and 32 are provided at opposite ends ofthe opening adapted to engage the bearings between them and accuratelycontrol its position in the opening. In the bracket 25- however, as thepressure due to the operation of the machine always tends to separatethe members 4 and 5, a suitable pocket is provided at the end of theopening 29 adjacent the bearing 28 and a spring 33 is positioned withone end in the pocket and its opposite end projecting into the opening29 adapted to engage the bearing to resiliently force the same towardthe opposite end of the opening. An adjusting screw 34 is provided inthe opposite end of the opening to engage the bearing and accuratelylimit its movement in that direction.

The members 4 and 5 may be secured to the shafts 1 and 2 in any suitablemanner. In the form shown, a fixed key or projection 35 is provided uponthe shaft 1 and a corresponding slot is formed in the hub 10 of themember 4 to cooperate with the projection 35 to prevent rotation betweenthe shaft and member. A set-screw 36 is also provided in the hub,arranged to engage the projection 35 or other suitable portion of theshaft and prevent longitudinal movement between the head and shaft.

The member 5 may be attached to the shaft 2 in the manner abovedescribed, but it is obvious that in a device of this charac ter it isdesirable that the cutting edge of the cooperating blades 6 shouldaccurately meet to secure the most satisfactory operation. For thisreason means are preferably provided for adjusting the rotary positionof one of the heads upon its shaft. In the other form shown, suitableslot-s 37-37 are provided'in that portion of the shaft 2 projectingbeyond the bearing 30 and a pair of set-screws 38 and 39 are provided inthe hub 10 of the member 5 each arranged to enter one of the slots andengage the part 40 of the shaft so that by loosening one setscrew andtightening the other the member 5 may be slightly rotated upon the shaftso as to adjust the relation of the blade 6 in the head 5 with thoseupon the head 4.

The cover plate or cam 18 may be supported in any desired manner. In theform shown a plurality of arms 45 are rigidly secured at one end to theplate 18 and at their opposite ends to the bracket 25. The space in thecover plate 18 for the head 5 is preferably of suitable form to permitsufficient lateral adjustment of the head to suit the different kinds orconditions of material to be operated upon.

The cams 17 may be rigidly supported in position within the heads 4 and.5 in any desired manner. In the form shown, each cam is provided with astem 46 positioned slightly to one side of its center line with the sideof the stem adjacent the center line slightly wider than the oppositeside and adapted to be engaged by astationary member extending into thechamber 12 for this purpose. Any suitable means 'may be pro vided forengaging the stem 46 to support the cams 17 in position. As shown acylin-- drical tubular member 47 is provided having a jaw or face A8 atone end formed to cooperate with'the stem 46 (see Figs. 5 and 6). A rod49 is also provided formed to snugly fit'the interior of the part 47 andprovided with a head 50 preferably of substantially the same diameter asthe part 47 and having a jaw or face 51 adapted to cotjperate with thejaw 48 to form a substantially dove-tail clamp of suitable size and formto engage the shank 4:6.

The relative position of the parts A? and 49 to produce the desiredclamping action may be controlled in any suitable manner. In the formshown, the rod 49 is of sufficient length to extend entirely through themember 47 and its extremity is threaded and provided with a suitable nut56 adapted to bear against the end of the part 47 to draw the head 50firmly toward the part 47 to firmly clamp the stem 46 between them.

Any suitable means may be provided to support the parts 47 and 49 inposition. In the form shown, a stand 52 is provided upon the base plate26 with suitable bearings 53-53 formed therein each adapted to receivethe part 47. A set-screw 54 or other suitable means is provided in thewall of each of thebearings 53 adapted to engage the part 4C7 to rigidlyhold the same in position in the bearing.

The free end of each-0f the cam supports.

may be held against transverse movement in any desired manner to insurethe satisfactory operation of this portion of the device. In the formshown the central bore of each head extends entirely through the hub 10and plate 9, but the shaft upon which each head or member 4: and 5 ismounted does not extend to the inner face of the plate 9 thereby leavinga slight central recess in the plate 9 adapted to engage a port-ion ofthe head 50, which is formed to fit the recess, thereby rigidlysupporting the cam in position. As shown a project-ion 55 is providedupon the central portion of the plate 9 within the chamber 12 toincrease the depth of the recess above described.

Any suitable means may be provided for rotating the shafts 1 and 2. Inthe form shown, a pair of gears 5 57 are mounted upon and rigidlysecured to the shafts 1 and 2 respectively and a drive shaft 58 isrotatably mounted in suitable bearings upon the brackets 24 and 25 witha pinion 59 rigidly secured thereto and arranged to mesh with one of thegears 57. Any suitablemeans may be provided for rotating the shaft 58.As shown a belt-pulley 60 is rigidly secured to the shaft so that mydevice may be connected by a belt or other suitable transmitting meansto any suitable source .of power (not shown) for operating the same. Ifdesired a similar pulley 61 may be, loosely mounted upon the shaft 58 sothat when it is desired to stop the machine the driving belt may beshifted to this loose pulley. A belt shifter 62 of the usual "form isshown in suitable brackets upon the plate 26 for directing the belt fromone pulley to the other.

The material after passing between the heads 4: and 5 as hereinbeforedescribed is received upon a carrier or belt 23 which moves it to anydesired point and'discharges the separate pieces into a suitablereceptacle. The conveyer may be of any desired form or construction. Inthe form shown the belt 23 is arranged upon a pair of pulleys 63 and 64suitably arranged to hold the belt at the proper tension. The pulley 63is secured to a shaft 65 rotatably mounted in suitable bearings upon thebrackets 24.- and 25. A gear or pinion 66 is also secured to the shaft65 and arranged to mesh with the pinion 59 to drive the conveyer. Thepulley 64: is secured to a shaft 67 rotatably mounted in suitablebearings upon a stand 68 at the opposite or discharge end of theconveyer. The upper portion of the belt 28 extends through a box,trough, or other suitable means 69 with walls or parts provided on eachside of the belt adapted to hold the material upon the belt until itreaches the end of the conveyer and is discharged.

In the preferred construction shown the heads 4 and 5 rial passingbetween them is not entirely severed, and the conveyer 23 is ofsufficient length to permit the material to harden sufficiently, so thatwhen it arrives at the end of the conveyer the material will break apartas it leaves the conveyer. Any suitable means may be provided to insurethe cooling or hardening of the material upon the conveyer. In the formshown an air pipe 70 is provided attached to a blower or otherconvenient source of compressed air, (not shown) and extends preferablysubstanti ally parallel to and slightly above the box or trough 69. Aplurality of openings or nozzles 71 are provided in the bottom of thepipe 7 0 by which the air from the tube is directed upon the material inthe trough. The end 7 2 of the pipe 70 is preferably only slightlycontracted or left entirely open, and so positioned as to direct a blastof air into the receptacle arranged for receiving the severed materialfrom my machine to prevent the warmth of the interior of the materialfrom tending to soften its exterior.

As shown a slide 73 is provided upon the are so adjusted that thematestand 68 and a suitable beater 74 is provided having a plurality ofarms 75 adapted to successively strike the material passingover thepulley 64: to insure the detachment of the severed pieces. Each of thearms 75 is preferably provided wit-h a brush or wiper 76 at its outerend for engaging the material so as to avoid breaking or marring thesame.

Any suit-able means may be provided for rotating the beater 74. In theform shown, the shaft 67 is extended beyond the bracket 68 and providedwith a gear 77 adapted to mesh with a pinion 78 rigidly secured to ashaft 7 9 rotatably mounted upon the stand 68 and to which the beater 74is also secured.

Having thus described my improvement, it is obvious that variousimmaterial modifications may be made in my device without departing fromthe spirit of my invention, hence I do not wish to be understood aslimiting myself to the exact form and construction shown.
